Bradford-based Yorkshire Building Society said its savings balances increased £1.1 billion year on year to £54 billion in 2025 “of which the increase in shares contributed £0.9bn.”
Yorkshire’s mortgage balances grew to £51.9 billion (2024: £49.7bn).
It delivered net lending of £2.2 billion (2024: £2.9bn) “driven by a higher level of gross lending than the prior year being offset by a greater level of product maturities.”
Net interest income was £869.8 million in 2025, increasing £133.3 million year on year. Net interest margin increased 16 basis points to 1.32% “supported by balance sheet growth, disciplined pricing and strong structural hedge performance.”
Management expenses increased £41 million to £407.6 million “in part due to higher levels of strategic investment, but also due to the continued growth of the business, inflation and investment in technology to support future resilience and efficiency.
On a statutory reporting basis, profit before tax was £377.9m (2024: £383.7m).
Overall, savings rates provided were on average 0.62 percentage points higher than the market average over 2025 (2024: 0.90 percentage points higher), equating to £313 million of additional interest paid.
CEO Susan Allen said: “Yorkshire Building Society delivered a solid performance for the year ending December 2025, growing our mortgage and savings balances sustainably and sharpening our Purpose, Real Help with Real Life, to set a clear path for the future.
“We continued to provide our members with above market average savings rates and went further to make good homes possible for more people. We launched targeted, innovative products to help overcome the challenges people face in finding a good home and building financial wellbeing.
“With economic challenges likely to remain in 2026, our renewed Purpose – and the support we offer our customers and communities as one of the UK’s biggest mutuals – matters more than ever.
“I am proud of the Society’s achievements and confident it is well-placed to keep supporting members and customers for decades to come.”
